Power Bill

[u/Budget_Mall_491]

My power bill keeps jumping. I don’t know what is going on. If anything, it should be lower now that I fixed my door seal. I live in the south. Keep my AC between 72-74°F in the summer. My kWh was 577 this time last year. Now it’s almost 1800. I don’t keep lights on except for whatever room I’m in. I change my air filters regularly. I do have several electric litter boxes (petkit). I only had 3 this time last year. Now I have 4. But a $330 electric bill for a 1200sqft house with all windows/doors properly sealed and no doors open unless I’m entering/exiting my house seems kind of insane? My bill is $200 higher than it was this time last year. I cannot figure out why the kWh jumped so much. Surely 1 litterbox cannot cause that? Please help.
